Openage: Problems building after removing Anaconda

[tejasjadhav]

Operating system: Ubuntu 16.04 (64-bit)
System Python Path: /usr/bin/python
Anaconda Path: /opt/anaconda3/bin/python

I forked this repository and pulled the latest code on my local machine. I had Anaconda installed already at /opt/anaconda3 with its binary path in my $PATH variable. When I first ran ./configure I had some issues with Anaconda (sorry I don't remember what issues I had). So, I decided to switch my Python interpreter to the one that comes with Ubuntu at /usr/bin/python. I removed Anaconda's Python Path from my $PATH variable in .zshrc, .bashrc and .bashrc_profile and restarted my machine. However, when I ran ./configure again, it still picked Anaconda's Python binary instead of /usr/bin/python. I even ran python manually in the same session but it correctly picked Ubuntu's Python binary instead of Anaconda's.

I got annoyed and removed Anaconda completely and this time it correctly picked Python binary from /usr/bin/python. But, I started getting other issues now. It seems the build system was still looking for Anaconda's libraries (I don't know why and how). The build system even had couple of issues with libfreetype6-dev library which could be solved only by symlinking the include files in the right places

But now, I'm stuck with this nasty one.

make[3]: *** No rule to make target '/opt/anaconda3/lib/libfontconfig.so', needed by 'libopenage/libopenage.so.0'.  Stop.
CMakeFiles/Makefile2:1482: recipe for target 'libopenage/CMakeFiles/libopenage.dir/all' failed
make[2]: *** [libopenage/CMakeFiles/libopenage.dir/all] Error 2
Makefile:138: recipe for target 'all' failed
make[1]: *** [all] Error 2
Makefile:33: recipe for target 'build' failed
make: *** [build] Error 2

I've completely removed Anaconda and which python returns /usr/bin/python. Does anyone has a slightest idea of what's going wrong?

I assume cmake chose /opt/anaconda3/lib/libfontconfig.so to satisfy the fontconfig dependency (which should not have happened). After removing Anaconda, this file does not exist, so cmake tries to build it. This obviously won't work.
Try make mrproper && ./configure. It might just work since Anaconda is no longer there.

However, we need to investigate why cmake found Anaconda's libfontconfig and how to suppress that.

@zuntrax Thanks a ton, mate! make mrproper && ./configure solved it. If I can reproduce Anaconda's issue again in future, I'll definitely create another issue and keep you'll updated,
